Casting & Forging
Many heavy industries value cast iron for adaptable properties that allow structural change based on the alloying elements.
Higher carbon content and silicon give iron greater castability in part design from ounces to tons when compared to steel. The versatile traits of ferrous metals provide markets with the opportunity for reduction in cost, defects, and time.
Our metal casting methods include:
- Lost wax/Investment & Lost Foam Casting (all materials) up to 150KG
- Sand Casting (ideal for large multi-ton parts)
- Pressure Die Casting
Customers benefit from our decades of experience in robust supply chain management in addition to strong offshore manufacturing capabilities for iron and other metals such as aluminum and steel.
We also offer industrial OEM castings and forgings made per client engineered drawings.
Cast Iron Parts Are Suited to Various Heavy Industries
Easily molded into numerous shapes and sizes based on industrial requirements, cast iron is utilized throughout a wide range of markets such as agriculture, automotive, construction, mining, oil & gas, and transportation.
Advantages of using cast iron in parts and assemblies include:
- Abrasion resistance
- Anti-vibration/damping capacity (Ex: metal-to-metal contact in heavy machinery)
- Easy integration (Ex: replacement parts)
- Excellent castability/fluidity
- Low melting point
- Low stress concentration
- Minimal maintenance
- Tensile strength
- Thermal conductivity
While many iron castings are used without heat treatment, they can be heated to enhance the overall properties.
Ferrous Alloy Casting for Heavy Industrial Applications
In order to support different product specifications across markets, AllTech offers the following selection of ferrous alloys for heavy industrial manufacturing:
Ductile iron (nodular iron)
- Unique properties from carbon, magnesium, and other alloys
- Graphite molecules form in spheres or nodules
- Impact resistant
- Can fabricate large, complex shapes
- Used in pipes, axles, cylinders, gears, pumps, steering knuckles, valves, etc.
- Categorized by flake shape of graphite molecules
- Great wear resistance and higher tensile strength
- Thermal conductivity
- Higher vibration damping capacity than steel
- Easier to machine than other cast irons; used in gears, weights & counter-weights, hydraulic components, machinery bases, etc.
- Forms when carbon atoms combine with iron to create iron carbide (cementite)
- Appears white when cut due to lack of graphite
- Harder than gray iron with less silicon; high compressive strength; abrasion and wear resistant
- Ni-Hard, a popular grade, has chromium and nickel alloys
- Often used in crushers, grinders, slurry pumps, shell liners, shot blasting nozzles, lifter bars, etc.
